Abstract

A locating device, particularly a handheld locating device, includes a housing, a display unit, and a locating unit, which is provided in order to detect a presence of an item arranged in an examination object by means of a measurement signal and which comprises an arithmetic unit. The arithmetic unit determines an orientation of an item image relative to a reference variable.

Claims

1. A locating device comprising:

a portable, handheld housing having dimensions that define a reference variable, the housing having a two-dimensional housing surface;

a display unit; and

a locating unit configured to detect presence of objects in a region of an examination object located in front of the housing surface using a measurement signal and includes a computation unit configured to generate an item image for the item from the measurement signal of the region currently located in front of the housing surface, the item image having at least two dimensions and depicting at least a profile of the item,

wherein the display unit is configured to display the item image including the profile of the item, and

wherein the computation unit is configured to determine an orientation of the item detected in the examination object with respect to the reference variable of the housing using the item image generated by the computation unit.

2. The locating device as claimed in claim 1, wherein the computation unit is configured to map the item image onto a two-dimensional space defined with reference to the dimensions of the housing surface.

3. The locating device as claimed in claim 2, wherein the computation unit is configured to detect the orientation of the item in the examination object with respect to the dimensions of the housing surface.

4. The locating device as claimed in claim 3, wherein the locating unit has at least one inclination sensor which is configured to detect an orientation of the reference variable with respect to gravity by detecting gravitational acceleration.

5. The locating device as claimed in claim 1, wherein the display unit has at least one display element which is intended to display the orientation of the item image with respect to the reference variable.

6. The locating device as claimed in claim 5, wherein the display element includes a first display element for displaying the orientation of the item image separately from the item image, and a second display element for displaying the item image.

7. The locating device as claimed in claim 5, wherein the display element is formed by a light emitting diode.

8. The locating device as claimed in claim 5, wherein the display unit has at least one display matrix.

9. The locating device as claimed in claim 5, wherein the display unit comprises a segment display.

10. A locating method using a locating device comprising:

using a portable, handheld locating unit to detect the presence of an item arranged in an examination object using a measurement signal;

generating an image of the region of the examination object located in front of a housing of the handheld locating unit from the measurement signal and a reference variable using a computation unit of the locating device, the image having at least two dimensions and depicting at least a profile of the item, the reference variable being defined by a housing of the locating device;

determining an orientation of the item with respect to the housing from the image of the item using the computation unit of the locating device; and

displaying the image using a display unit of the locating device.

11. The locating method of claim 10, further comprising:

emitting the measurement signal from a sensor unit into the examination object.
